Familiarize yourself with muscles in the body (Part 2)
By Davina Bagot
Kaieteur News – Your exercise efforts become much more effective as you learn the respective muscles of the body. One of the key advantages is that you gain a better understanding of which specific muscles need to be targeted to achieve your particular objective (s).
Last week we looked at muscles in the chest and back. In this week’s Fit-Nest column, we will explore the muscles found in the arms and shoulder as well as the abdomen.
For a lot of Guyanese, their exercise routines tend to focus heavily on the core (abdomen), as this is usually the area that stores the most fat. While some may be trying to gain that sculpted movie star-like ‘six pack’ (abs), doing abdominal exercises have proven to assist in the breathing process and the protection of your inner organs.
Obliques
The muscle group on the sides of the abdominals is known as the obliques. Movement of these muscles may result in several actions, but they are best known for their lateral flexion and rotation of the trunk known as a side bend. Their function is to help support the spine from the front. This means that they are vital in maintaining a good posture. Other important abdominal muscles are listed below.
Gluteus medius
One of three gluteal muscles, the gluteus medius, connects the ilium to the top of the femur. It controls the level of the hips and allows the thighs to rotate.
Gluteus maximus
The gluteus maximus as the name may suggest is the largest and outermost muscle of the buttock. It attaches to several places in the pelvis and thigh and allows you to extend your upper leg, spread it, and turn it outward.
Serratus anterior
These are a group of muscles connected to the rib cage, which help stabilize the shoulder.
Psoas major
The Psoas major muscles connect the lower part of the spine to the ilium and the femur and aids in flexing the hips.
Arm and shoulder muscles
Biceps
This muscle is found in the front of the upper arm. The biceps help control the motion of both the shoulder and elbow joints. At the elbow, the biceps are essential in lifting, and at the shoulder, they help with moving the arms sideways, forward and upwards. Basically, this muscle helps bend or curl the arm toward your body.
Triceps
The triceps are muscles in the back of the upper arm. These muscles help stabilize the shoulder joint and allow the elbow joint to be straightened. The triceps are utilized in passing and shooting a basketball, and help with finite movements such as in writing, drawing or even push and pull.
Deltoids
The deltoids, or delts, are known as the shoulder muscles. This muscle group is used on all side of body lifting motions. They provide support when you carry things and help keep carried items away from the motion path of the thighs. The deltoid muscle consists of 3 parts: anterior deltoid, medial deltoid, and posterior deltoid.
